ProSR: Process-Shaped Spatial Reasoning for Reliable Chain-of-Thought in VLMs arXiv:2605.25524v1 Announce Type: new Abstract: Reliable spatial reasoning remains a core bottleneck for vision-language models (VLMs). Existing mainstream training paradigms for spatial reasoning largely rely on outcome alignment or process imitation, lacking explicit constraints on the reasoning process, and therefore struggle to ensure genuine visual dependence and stable reasoning trajectories. In this paper, we c
